摘要：
Mg-doped ZnO (Mg;Zn;O, x=0-0.10)nanoparticles were prepared by sol-gel method. Structural characterization by X-ray diffraction （XRD） indicates that the lattice parameter a increases and c decreases linearly with the increase in Mg content （x） due to the substitution of Mg;for Zn;in ZnO lattice. The blueshift of Raman modes is observed, impling the increase in force constant of atom vibration in the Mg;Zn;O （MgZnO） nanoparticles. Resonant Raman spectra show longitudinal optical phonon overtones up to fifth order, revealing that the short part of the electron-phonon interaction is enhanced and long-range part is weakened by Mg doping.
